To all whom t may concern.'

zen of China, residing atCanton, China,

`have invented new and useful improve? ments in Polishing-Machines, of which the following is a specification.

This invention relates to improvements in polishing machines and has Particular application to amachine for polishing shoes, although I wish it to be undrstqod, that my invention, in its useful appllcatiii-may be employed for polishing silverware, brassware and other articles.

lln carrying out my invention, I'employ a brush capable of rotation and a polish container arranged above the brush and adaptedto deliver polish to the brush, in combination with a polishing roll arranged adjacent to the brush and adapted to be rotated, and an electric motor or other suitable driving means connected to the brush f parallel with Fig. .4, and

and the polishing roll and to the polish conl tainer so that in the operation of the motor polish will be fed to the brush and the brush and roll revolved. Suitable means is also provided for disconnecting the polish container from the motor so that the brush and polishing roll may be rotated without feeding polish to the brush. The brush, the polish container and the polishing roll and the motor for operating all of such parts are inclosed in a suitablecasing and supported in proper relative positions and the machine is small and compact and may be handled conveniently and easily so that tho polishing operation may be carried on rapidly and with a minimum eHort on the part of the operator.

Fig. 6 is a horizontal sectional view on the line (5-6 of Fig. 3.

Figs. 7, 8, 9 and 10 are invention.

`Referring' nowto the drawings in detail, 1 designates a substantially vrectangular vertical casing. Mounted upon the upper end of the casing is a removable covery 2 Vprovided with a handle. 3. In the present instance, one end edge of the cover 2 is hinged to the corresponding end wall of the casing, while secured to the other side wall of the casing is a split button 4 and pivoted to the adjacent end wall of lthe cover is a disk 5 formed with an opening 6 adapted to receive the button 4 so as to hold the cover 2 in closed position and enable the casing to be carried about by the handle 3 without swinging the cover to open position. rThe edge portion of the disk 5 opposite from that portion connected'tq the cover 'is detail views of the provided with a finger piece 7 whereby the disk may be swung to locking and unlocking posltionsand when the disk is swung to locking position the sections of the button 11 pass through the opening 6 and frictionally engage the opening to hold the disk in closed or locked position.

In the present instance, one side wall v of the casing 1 is capable of removal from the casing and the edges of the end walls corresponding to the edges of the removable sidewall are flanged inwardly as at 8 and have the confronting edges thereof formedwith longitudinal grooves 9 respectively and thesegrooves 9 receive the longitudinal edges of the removable side wall so that the side 4wall may be moved into and out of position so that access may be had to the interior of the casing. Secured to the bottom wall of the receptacle 1 centrally thereof are vertical standards 10 arranged alongside of the respec-` tive side Walls of the casing and terminating at a point approximately centrally of the height of the casing. Journaled in the upper ends of the standards 10 is a shaft 11 and formed on the shaft 11 at a point approximately centrally thereof is a pinion 12, while surrounding the shaft 11 and fixed thereto adjacent toV one end thereof is a relatively large pulley wheel`13. Suitably fastened to the bottom wall of the casin 1 at one side of the standards 10 is an e ectric motor 14: and fixed. to one end of the armaindicates a 4minal is connected ture shaft of the motor 14 is a pulley wheel 15 and trained over the pulley wheels 13 and 15 is an ,endless belt 16 whereby the motion will be transmitted from the armature shaft to the shaft 11. Secured to one Zend wall of the casing and projecting' into 'the latter above the motor 14 is a supporting plate 17 and mounted upon the supporting plate 17 is a dry cell-18. Mounted upon the outer side of said end wall 'of the casing. is an electric switch comprising, in the present instance, a strip 19 having one end bent 4at right angles to itself as at 20 and fastened to the casing is a contact stud 21 secured to the casing and disposed in the path of movement ofthe other end of the strip. Passing 'through the strip 19 and bearing against the adjacent end wall f the casing is a pin 22 and threaded upon the pin 22 between the casing and the strip is a. thumb disk 23 which may be rotated to permit of adjustment. Normally, the pin 22 acts to hold the strip 19 spaced apart from the stud 21 an the end of the strip adjacent to the stud 1s adapted to be forced into engagement therewith by means of the fingers. The contact stud 21 and the strip 19 are preferably insulated from the casing as shown in Fig. 3 of the drawings. One terminal of the dry cell 19. is connected to the contact stud 21 by means of a conductor 24, while the other terto one side of the motor by means of a conductor 25 and leading from the other side of the motor is a conductor 26 terminally connected to the contact strip 19. Thus. when the switch is actuated to closed position, the cell 19 is connected in circuit with the motor 14 and the latter operates to drive the disk 13 and the shaft 11.

Arranged upon the opposite side of the standards 10 is a polish container 27 adapted to collapse and expand after the fashion' of a bellows. Secured to the upper end of the polish container 27 i's a collar 28 and mounted upon the collar 28is a plate 29 projecting beyond the edge of the collar and having the projecting portions thereof formed. with openings. Passed through these openings are theu'pper ends of vertical guide rods 30 and rods are secured to the the lower ends of the bottom wall of thecasmg. These rods and the plate serve as guides for the container soas to facilitate the upwardand downward movement thereof. Fixed to the plate 29 and extending upwardly therefrom is a guide frame 31 embracing bar 32, which bar has-its edge formed with teeth '33 meshing with the pinion 12 on the shaft 11. Secured to the outer side of the rod or bar 32 is a tube 34 formed with a vertical slot3'5. 36'

formed with tube 34 and the other end the adjacent end wall threaded onto the projecting end of the rod projecting through respective side walls releasing rod having-one endA a ball 37 arranged within the of the casing and" openings 39, while rotatably mounted upon the cap 38 and of a shape conforming to that of the cap isa valve -40 provided with a handle 41 projecting through the end Wall of the casing. The .bottom wall of the .'vnlve 40 is formed with openings adapted'to be moved into and out ofregstration with the openings in the cap to control the discharge of the polish from the container. present instance, the plate 29 is formed with a filling opening 42 andv pivoted `upon the plate is a closure 43 movable to cover and Auncover the filling opening.

Secured to the bottom fwall of the casin 1 and depending therefrom contiguous to tie opposite sidewalls o the casing are hangers 44 arranged adjacent to one end wall of the casing, while depending from the bottom wall of the casing'contiguous to the and arranged adjacent of the casing are liangers 45. Journaled in the lower ends of the hangers 44 i's a shaft 46 upon which is rotatably mounted a brush' 47, while journaled in the lower ends of the hangers 45 to the other end wall In thel 1s a shaft 48 upon which is mounted a polishing roll 49. Keyed upon corresponding ends of the shafts 46 and 48 are pulley wheels 50 and trained over these wheels ,is an endless belt 51, while fixed upon both ends of the shaft 48 are pulley' wheels 52 and trained over the pulley wheels 52 and pulley wheels 53 on the respective ends of the armature shaft of the motor 14 are endless belts 54. By means of these belts 54 and 5l, it will be seen that motion is transmitted from the armature shaft to the shaft carrying the polishing roll and to the shaft carrylng the brush, thereby rotating the poland the plate 29 downwardly so that the polishv may be d1scharged from the container 27 through the registering' openin in the cap 38 and1 valve 40 onto the brush47. Simultaneously with the feeding of the polish onto the brush, motion is transmitted fromthe'motor to the polishing roll 49 and the brush 47 andthe polish lmay plied to the article bv means of the brush polished by means 47 and then the article vof the polishing roll 49.

en the machine is not in use, the brush are preferably inmeans of a cover 5 5 .adapted tobe and the polishing roll closed by armature shaftto the pul-` be apslipped over the lower end of the casing and having the ends thereof equipped with locking devices identical in construction with the lookin device for the cover 2.

After a suiiiclent quantity of polish has been delivered to the brush 47 and it is desired to operate the brush and the polishing roll without delivering more polish to the brush, the members 32 and 34 may be moved outwardly to disengage the rack teeth 33 from the pinion 12 by means of the releasing rod 36.

While I have herein shown and described one preferred form of my invention by way of illustration, I Wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modiication and variation may be made within the scope of the claims and without departing from the spirit of the invention.
